I picked up a 2012 Ecoboost supercrew w/ 6.5 ft bed back in march and have since put just over 12,000 miles on it. Of that, 1600 was a highway trip and 1100 of it was towing a ~5000 lbs trailer, all highway as well. leaving about 10k of normal driving or so. Tires have always been aired to 36 psi (door sticker says 35).

I definitely enjoy my truck and don't baby it but I also don't floor it off the line at every light and my rear tires are pretty much done for and will need to be replaced. I took my truck into the dealer for the first oil change around 5k miles and I am assuming they rotated the tires (still need to check the receipt).

I am shocked that they are already this far gone am I'm looking for a second opinion on if I am just crazy and apparently that bad of a driver or what. I'd expect the fronts to be more worn than the rears since they take all the braking force yet its the other way around.

Any thoughts? The extra picture is of the bad tire, passenger side rear. The two with better tread are the fronts.

Edit - tires are Goodyear Wrangler SR-A's with a 500 treadwear rating.

overinflated would be my guess since its worn in the middle. Bad alignment if indeed were rotated.

Spin'm much? LOL

I don't baby mine and I have 37800 miles on the truck with original tires (Pirreli). One thing I make a point not to do is spin the tires. Getting to old to buy tires every couple months. Had a 2003 Cobra that I couldn't get 5000 miles out of a set.

As much as I would like a more aggressive tire I am going to let these run there course.

If they rotated them I would be surprised by the amount of wear in the pictures.

Over inflated was my first thought too, but even the outside is worn pretty badly.

Door says 35 all the way around but with no weight in the rear maybe I should drop the backs down a bit?

I don't spin them, but I may be more aggressive than I feel like I am. Still seems like they should last a little longer than 12k miles.

That was my original thought but I had done a lot of testing of tires and wear characteristics with suspensions and air pressure for Hunter Engineering and found that slightly over inflated wear more evenly than correctly inflated. If he was really running 36 psi then I wouldn't be worried about it, that is what I was running in mine up until about 5000 miles ago. In WI the frost heaves in the concrete were too much and the rear of the truck was bouncing all over the place. I am running slightly lower than recommended now.

I don't know of any other way the rear tires could wear like that.

Over inflation, I'm not sure if a tire rotation would be done if you didn't ask for it. What brand of tire is that?

Goodyear Wrangler SR-A tires
